Scaling of setminus in xits

Scaling of setminus in xits

[Aditya Mahajan]

Hi,

\setminus does not scale properly in xits. I am not sure if it is a bug in 
the font or in ConTeXt.

\setupbodyfont[xits]
\starttext
$A \setminus B$
\stoptext

I don't have larger variants of that glyph, so it is not set to scale.
If you can find larger glyphs in STIX, I'll use that, but right now all
those slash/backslash-like glyphs confuse me (and STIX seems to have
wired shapes compared to similar glyphs in other fonts).

It should not scale, but the default size is too small. Compare the size 
of \setminus in xtis from that in cambria or even LM. Just going by the 
glyph table at stix site, set minus should correspond to glyph 3991 in 
STIXGeneral.otf. I do not know how to view that glyph, so do not know if 
xtis uses the right glyph or not.

Yes, that what I meant by wired shapes (the slants are sometimes
different from similar slashes in other fonts).

If you search for 02216 glyph, you will see there is a variant glyph in
STIXVar.otf, if you think that variant should be the default I can do
that and make the current one available as an optional glyph variant (I
think I should check the rest of the STIXVar.otf font too, it was on my
todo for a while now).

Dumb question, but how do I check a specific glyph in a font. I tried

\getglyph{STIXGeneral.otf}{\char2216}

and
\font\STIX=STIXGeneral.otf
\STIX \char2216

but both of them give a blank character.

\STIX \fontchar{unicode slot or glyphname}

Use hex numbers:

\starttext
\definedfont[file:STIXGeneral.otf]\char"2216
\definedfont[file:STIXVar.otf]\char"2216
\stoptext
